Article
Data transmission tends to be neglected when considering the carbon efficiency of systems, even though the electricity usage of data networks as a whole is as large, or larger, than that of data centers. Accounting for carbon cost of the movement of data is hard, and is often assumed to be the responsibility of the receiver or an intermediate provi...

Network defence is an elusive art. The arsenal to defend our devices and networks from attack is constantly lagging behind the latest methods used by attackers to break into them. To counteract this trend, we developed a distributed approach comprised of collaborative endhost detectors. Simulations reveal dramatic improvements over stand-alone dete...
Conference Paper
Full-text available
We describe a method to detect botnet command and control traffic and individual end-hosts. We introduce the notion of “destination traffic atoms” which aggregate the destinations and services that are communicated with. We then compute the ”persistence”, which is a measure of temporal regularity and that we propose in this paper, for individual de...

Reliable data multicast is problematic. ACK/NACK schemes do not scale to large audiences, and simple data replication wastes network bandwidth. Fcast, “file multicasting”, combines multicast with forward error correction to address both these problems. Like classic multicast, Fcast scales to large audiences, and like other FEC schemes, it uses band...
Thesis
Full-text available
With the exponential growth of the Internet, there is a critical need to design efficient, scalable and robust protocols to support the network infrastructure. A new class of protocols has emerged to address these challenges, and these protocols rely on a few key techniques, or micro-algorithms, to achieve scalability. By scalability, we mean the a...
